Requirements

Python

Python ≥3.9 is required. An older version of Python will not work.

Usage

To install the package, run:

$ pip install dagdshort

Usage example:

>>> import dagdshort

# Setup
>>> shortener = dagdshort.Shortener(user_agent_suffix='<YourGitUsername>/<YourGitRepoName>', max_cache_size=256)

# Shorten
>>> long_urls = ['https://github.com/impredicative/dagdshort/', 'https://pypi.org/project/dagdshort/']
>>> shortener.shorten_urls(long_urls)
{'https://github.com/impredicative/dagdshort/': 'https://da.gd/W9s06',
 'https://pypi.org/project/dagdshort/': 'https://da.gd/KtGTB'}

# Show cache info
>>> shortener.cache_info
{'Shortener._shorten_url': CacheInfo(hits=0, misses=2, maxsize=256, currsize=2)}

To obtain the fastest response, URLs must be shortened together in a batch as in the examples above. Up to 8 concurrent workers are automatically used. The max limit can, if really necessary, be changed by setting config.MAX_WORKERS before initializing the shortener.

Errors

If a "Blacklisted long URL" error is experienced for a reasonable website which should not be blacklisted, it can be reported here. As an example, see this issue.
